[0006] As a preferred technical solution of the present invention, a row of fixed support legs is fixed to the bottom surface of the rectangular box along its length direction.

[0007] As an optimal technical solution of the present invention, the upper end of the mounting slot is inclined toward the sewage inlet pipe; the mounting slot includes a rectangular column; the rectangular column is provided with a non-conductive rectangular guide groove which is set in an extension direction at its upper end; the side end of the isolation filter plate is inserted into the rectangular guide groove.

[0008] As a preferred technical solution of the present invention, the isolation filter plate includes a rectangular plate body; the lower half of the rectangular plate body is evenly distributed with filter holes; and a reinforced middle frame is fixed on the surface of the rectangular plate body.

[0009] As an optimal technical solution of the present invention, a guide inclined plate is fixed between the inner wall and the inner bottom surface in the length direction of the rectangular box, and the guide inclined plate is placed at the sediment discharge groove; a triangular support plate is arranged between the bottom of the guide inclined plate and the inner bottom surface of the rectangular box.

[0015] 3. The utility model uses a guide inclined plate at the sediment discharge slot to cooperate with the vibrator to promote the bottom sediment to gather toward the center and be discharged through the screw conveyor, while reducing the blockage problem caused by adhesion, ensuring the long-term stable operation of the system.

[0016] 4. The utility model adds a horizontal baffle at the clean water outlet, so that the water flow speed entering the area is slowed down and evenly distributed, thereby avoiding the extraction of liquid containing more suspended solid components in the lower layer, ensuring that the final discharged water quality meets the standards.

DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0028] See also Figure 1-5As shown, the present invention is an industrial wastewater purification device, which aims to provide a sedimentation purification treatment for wastewater with large amounts of sludge, facilitating the stable discharge of heavy sludge. Its structure includes a sedimentation tank 1. A row of inclined isolation filter plates 2 are installed between opposing inner walls along the length of the sedimentation tank 1. The sedimentation tank 1 comprises a rectangular housing 11. A sediment discharge notch 12 is defined along the center of the bottom of the rectangular housing 11 along its length. A spiral auger conveyor 3 is installed along the bottom of the rectangular housing 11 along its length, and the portion where the auger conveyor 3's tube connects to the bottom of the rectangular housing 11 is connected to the sediment discharge notch 12. An extended discharge pipe 31 is installed at the output port of the auger conveyor 3, and a butterfly valve 4 is mounted on the extended discharge pipe 31. A sewage inlet pipe 13 is fixedly inserted through one end of the rectangular housing 11. When sewage enters the sewage inlet pipe 13, it is treated with flocculant. A clean water outlet pipe 14 is fixedly inserted through the other end of the rectangular housing 11. A row of symmetrical mounting slots 15 are fixed to opposite inner walls along the length of the rectangular housing 11. The upper ends of the mounting slots 15 are angled toward the sewage inlet pipe 13. The mounting slots 15 comprise a rectangular cylinder. A non-conductive rectangular guide groove extends from the upper end of the cylinder. The side ends of the isolation filter plates 2 are inserted into these rectangular guide grooves.

[0029] By installing a spiral auger conveyor 3 for conveying sediments such as silt at the bottom of the sedimentation tank 1, the butterfly valve 4 is opened and the spiral auger conveyor 3 is started after the sediment thickness reaches the thickness that needs to be cleaned. The spiral auger blades slowly push the sediment to the butterfly valve 4 for output, and the thick sediments such as silt in the sedimentation tank 1 are quickly discharged.

[0030] The isolation filter plate 2 includes a rectangular plate body 21. The lower half of the rectangular plate body 21 is evenly distributed with filter holes 22. A reinforced middle frame 23 is fixed to the surface of the rectangular plate body 21.

[0031] A row of isolation filter plates 2 are installed in the sedimentation tank 1. Half of the isolation filter plates 2 are closed plates, which are used to reduce the movement area of ​​the lateral space of the sedimentation tank 1. The other half is set as dense filter holes 22 to intercept large particle precipitation and larger flocculants. The arrangement of multiple isolation filter plates 2 is conducive to suppressing the flow of debris and improving its sedimentation efficiency.

[0032] A diverter plate 16 is fixed between the inner wall and the inner bottom of the rectangular box 11 along its length, and is positioned at the sediment discharge slot 12. A triangular support plate 17 is positioned below the diverter plate 16 and between the inner bottom of the rectangular box 11. The diverter plate 16 facilitates the movement of sediment from the bottom of the sedimentation tank 1 toward the central sediment discharge slot 12, facilitating the cleaning and discharge of the auger conveyor 3 and reducing manual intervention to achieve a better cleaning effect.

[0033] At least two vibrators 5 are mounted on the bottom surface of the guide plate 16. A window 18 for mounting the vibrators 5 is provided on the side of the rectangular box 11. The vibrators 5 vibrate the guide plate 16, effectively accelerating the removal of sediment stuck to the guide plate 16.

[0034] A horizontal baffle 19 is fixed to the inner wall of the rectangular box 11 below the clean water outlet pipe 14. The baffle 19 is installed below the clean water outlet pipe 14 to adjust the water flow into the clean water outlet pipe 14 in multiple horizontal directions, so that the water at the upper level is relatively clear and the clean water outlet pipe 14 is prevented from extracting the water containing flocculent sediment below.

[0035] For installation occasions without an installation foundation, a row of fixed support legs 110 are fixed along the length direction of the bottom surface of the rectangular box 11. The height of the fixed support legs 110 is used to ensure smooth sludge discharge below.
